OK, I'm gonna start getting caught up to what I've put on Flickr.
My dad got this excellent router table for Christmas. We used it to put a nice edge on all of our boards. There's a shim behind the left half of the fence (the board moves to the left), that matches the depth of the cut, so the board hugs the fence on both sides of the bit.
This is not an action shot. When we actually cut off the ends, we were more careful to make it square. Of course, as mentioned above, square is one thing, the right length is another.
We tried and failed to use the router table to cut the boards to width. I think we were pushing the board in the wrong direction, but in the meantime we finished the job on the tablesaw, which is the right tool for he job anyway.
Starting to cut the corner sides. They will be mitered, and the saw tilts to 45 degrees. I marked 12 inches on one side, used a spare bit of 45 degree wood to mark the edge, and marked where to make the cut.
When making the cut, I used a square to make sure that the saw guide was square, while my dad made the cut.
Flip the board, and cut another 45 degrees on the same line.
A 90 degree notch was cut out.
The grain remains unbroken across the joint.
Looks good.
